Copy code The code is as follows:
if (!preg_match("/^(http|ftp):/", $_POST['url'])) {
$_POST['url'] = ' http://'.$_POST['url'];
}
This code first uses a regular expression to check whether there is "http" or "ftp" and colon ":" in the string. If not, in the character Add "http://" before the string
